fix(review): address code review findings before merge

- update_prep_task: move whitelist guard above filter so invalid column
  check runs on raw kwargs (was dead code — set(filtered) - allowed is
  always empty); fixes latent SQL injection path for future callers
- main.py: move register_kiwi_programs() into lifespan context manager
  so it runs once at startup, not at module import time
- MealPlanView.vue: remove debug console.log stubs from onSlotClick and
  onAddMealType (follow-up issue handlers, not ready for production)
